From fd4366c0c11e7dda3fd5e2e70ee65613cd4dbdd8 Mon Sep 17 00:00:00 2001 From: Emily Deng Date: Thu, 9 Aug 2018 10:03:04 +0800 Subject: [PATCH 5053/5725] drm/amdgpu/sriov: give 8s for recover vram under RUNTIME Extend the timeout for recovering vram bos from shadows on sr-iov to cover the worst case scenario for timeslices and VFs Under runtime, the wait fence time could be quite long when other VFs are in exclusive mode. For example, for 4 VF, every VF's exclusive timeout time is set to 3s, then the worst case is 9s. If the VF number is more than 4,then the worst case time will be longer. The 8s is the test data, with setting to 8s, it will pass the TDR test for 1000 times.
